Definitions
- the present invention relates, in general, to an anti-rotation push tab for a medical device. More specifically, the anti-rotation push tab is especially adapted for use with intravenous catheters, as well as catheter introducers and guidewire introducers.
- An intravenous (IV) catheter is typically mounted over an introducer needle having a sharp distal tip in order to properly insert an IV catheter into a patient. At least the distal portion of the catheter tightly engages the outer surface of the needle to facilitate insertion of the catheter into the blood vessel. The distal tip of the needle preferably extends beyond the distal tip of the catheter.
- PIVCs have issues with stability of the catheter hub when advancing it and are prone to free spinning on the insertion needle during the insertion process.
- the catheter hub includes a push tab to aid in advancing the catheter hub. As the catheter hub advances, in some cases, it experiences rolling where the catheter hub spins along the axis of the insertion needle. This can cause a problem when the push tab rotates out of reach of the finger being used to advance the catheter hub.
- an edge is provided on the catheter hub so that the user can advance the catheter hub regardless of its angular position. There is a concern in that the edge becomes quite uncomfortable to a patient when the catheter hub has been taped down at the insertion site thus forcing the edge against the patient's soft tissue.
- Embodiments of the present invention provide a platform that pushes on the user's finger when the catheter begins to rotate and allows the user's finger to resist the rotation and also steer the catheter back to the neutral starting position. Free spinning of the catheter hub can be prevented without making any other design compromises or increasing the cost of the design.
- a medical device comprising a hub or housing having a push tab including a main portion extending radially from an upper surface of the hub or housing, and at least one anti-rotation feature for resisting rotation of the hub or housing.
- a cannula is directly or indirectly connected to the hub or housing.
- the medical device may be a catheter, the cannula may be a catheter tube, and the hub or housing may be a catheter hub or an introducer needle tip shield for the catheter.
- a medical device comprising a housing having a push tab including a main portion extending radially from an upper surface of the housing, and at least one anti-rotation feature for resisting rotation of the housing, and a cannula connected to the housing.

Description
- This application is a continuation of U.S. Nonprovisional application Ser. No. 16/920,003, filed on Jul. 2, 2020, which is a continuation of U.S. Nonprovisional application Ser. No. 15/467,929, filed on Mar. 23, 2017, which claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. 62/323,525, filed on Apr. 15, 2016. Each of these applications is hereby incorporated by reference in its entireties.
- The present invention relates, in general, to an anti-rotation push tab for a medical device. More specifically, the anti-rotation push tab is especially adapted for use with intravenous catheters, as well as catheter introducers and guidewire introducers.
- An intravenous (IV) catheter is typically mounted over an introducer needle having a sharp distal tip in order to properly insert an IV catheter into a patient. At least the distal portion of the catheter tightly engages the outer surface of the needle to facilitate insertion of the catheter into the blood vessel. The distal tip of the needle preferably extends beyond the distal tip of the catheter.
- Although typical IV catheter and introducer needle assemblies generally perform their functions satisfactorily, they do have certain drawbacks. Some PIVCs have issues with stability of the catheter hub when advancing it and are prone to free spinning on the insertion needle during the insertion process. Oftentimes, the catheter hub includes a push tab to aid in advancing the catheter hub. As the catheter hub advances, in some cases, it experiences rolling where the catheter hub spins along the axis of the insertion needle. This can cause a problem when the push tab rotates out of reach of the finger being used to advance the catheter hub.
- In some cases an edge is provided on the catheter hub so that the user can advance the catheter hub regardless of its angular position. There is a concern in that the edge becomes quite uncomfortable to a patient when the catheter hub has been taped down at the insertion site thus forcing the edge against the patient's soft tissue.
- Accordingly, it is an aspect of the present invention to provide features that oppose the rotational movement of a medical device in relation to the user's finger. In the case of an IV catheter, this can enhance the stability of the catheter during insertion, hooding, and threading. Embodiments of the present invention provide a platform that pushes on the user's finger when the catheter begins to rotate and allows the user's finger to resist the rotation and also steer the catheter back to the neutral starting position. Free spinning of the catheter hub can be prevented without making any other design compromises or increasing the cost of the design.
- The foregoing and/or other aspects of the present invention are achieved by a medical device, comprising a hub or housing having a push tab including a main portion extending radially from an upper surface of the hub or housing, and at least one anti-rotation feature for resisting rotation of the hub or housing. A cannula is directly or indirectly connected to the hub or housing. The medical device may be a catheter, the cannula may be a catheter tube, and the hub or housing may be a catheter hub or an introducer needle tip shield for the catheter.
- The foregoing and/or other aspects of the present invention are also achieved by a medical device, comprising a housing having a push tab including a main portion extending radially from an upper surface of the housing, and at least one anti-rotation feature for resisting rotation of the housing, and a cannula connected to the housing.
- Additional and/or other aspects and advantages of the present invention will be set forth in the description that follows, or will be apparent from the description, or may be learned by practice of the invention.

The first andsecond extension catheter hub 402 such that as the catheter rotates either clockwise or counterclockwise, either thefirst extension 414 or thesecond extension 416 will contact the skin of the patient and prevent further rotation, while thepush tab 412 is still in contact with the clinician's finger, allowing advancement. -
FIG. 5 illustrates acatheter hub 502 with a more deeply sculptedpush tab 512 formed on an upper surface of thecatheter hub 502. The deep-sculptedpush tab 512 includes a wall-like main portion extending radially from an upper surface of thecatheter hub 502. Afirst extension 514 and asecond extension 516 extend from the wall-like main portion of thepush tab 512. Thefirst extension 514 andsecond extension 516 both extend proximally on thecatheter hub 502 and curve toward the main portion of thepush tab 512 to cradle a user's finger by engaging the sides of the clinician's fingers and allow the user to control lateral motion and rotation. Thefirst extension 514 and thesecond extension 516 act as anti-rotation members that counteract rotation of thecatheter hub 502. - Regarding
FIG. 6 , acatheter hub 602 incorporating acatheter 620 is illustrated. Apush tab 612 is formed on an upper surface of thecatheter hub 602. As illustrated inFIG. 6 , thepush tab 612 is configured as a wall-like main portion extending radially from an upper surface of thecatheter hub 602. Afirst cradling tab 614 extends from a first side of thepush tab 612 perpendicular to a plane of thepush tab 612. Asecond cradling tab 616 extends from a second side of themain portion 612 perpendicular to a plane of thepush tab 612. Thepush tab 612,first extension 614 andsecond extension 616 thereby form a cradle shape to resist catheter hub rotation where thefirst extension 214 and thesecond extension 216 act as anti-rotation members that counteract rotation of thecatheter hub 202. -
FIG. 7 illustrates awing catheter hub 702 incorporating aflexible IV catheter 720 andwings 730. Anpush tab 712 is formed on an upper surface of thecatheter hub 702. As illustrated inFIG. 7 , thepush tab 712 includes a tall wall-like main portion extending radially from an upper surface of thecatheter hub 702.Anti-rotation push tab 712 provides a cradling effect for the user's finger to aid insertion stability. - A
first rib 714 parallel to the plane of thepush tab 712, but shorter in height, extends from an upper surface of thecatheter hub 702 and is spaced proximally from to thepush tab 712. Asecond rib 716 and athird rib 718, also shorter in height than thefirst rib 714, may also extend from an upper surface of thecatheter hub 702 parallel to the plane of thepush tab 712. Theribs Ribs -
FIG. 7 illustrates threeribs single rib 814 may be utilized to provide the necessary anti-rotational effect as illustrated inFIGS. 8A and 8B . The rib(s) 714, 716, 718 and 814 should be a distance from thepush tab 712/812 where the rib is far enough from thepush tab 712/812 to contact a user's advancing finger pad to provide stability but not so close that the finger pad does not contact the rib. Thecatheter hub 802 may be manufactured with or withoutwings 830 as shown inFIGS. 8B and 8A , respectively. - The foregoing detailed description of the certain exemplary embodiments has been provided for the purpose of explaining the principles of the invention and its practical application, thereby enabling others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to the particular use contemplated.
